Hi all -
I'm preparing for an upcoming migration to Jira Cloud and I'm looking for a solution that allows for migrating Jira project data into a cloud instance that has existing data. The JCMA is the preferred mechanism when migrating to a new instance, but what's the best solution when migrating projects to an existing site? As I understand, JCMA will perform a full site replacement, which will not work in my scenario.
I'd rather not do a CSV import as I want to retain history, comments, attachments, etc.
Has anyone successfully done this? What tools or approaches did you use?
